Bioware and Rockstar are no where near the top 10. ALhough they will probably be on the list.

Rockstar is without a doubt the most over rated game developers of all time. They have had ONE successful franchise, all other attempts at games have been complete trash, warriors, bully, table tennis. Even GTA is a POS game. I will give them that GTA3 was revolutionary and created a new genre, but they haven't done anything since except for reuse the same model each game therafer.

Bioware is the same thing. All of their RPGs are exactly the same. They are great if you play one, but after the 4rth game you play you realise its the same as all their others but with just different characters.

Blizzard will have to be in the top 3 I think, with RTS, RPG, MMO, being defined by them they would have to be.

Also if you think that Nintendo is not #1 by head and shoulders your crazy. Nintendo has defined what video games are. They have created more genres, and defined exellence in existing genres more then any other company. The DS has been out for 4 years and no one has come close to being able to utilize it to its fullest as nintendo has with Zelda PH. They are truly the world leaders in game development.

Everyone else must have forgotten that the Mario franchise, alone, has sold almost 200 million games.

I also like Sega at #2.

In fact, my only real qualm with your list is that, at #3, I would have Square Enix, and totally drop Sony. Final Fantasy, as of late, hasn't had the wonderful experiances we used to see, but they're not so far removed from the first 7, which were all, at least, very good, that we can discount them yet.

You cant call square #1 because they only do RPGs. They make the best RPGs of anyone ever, but still thats all they do. Too many bad attemtps at other genres to consider them the #1 publisher of all time. My favorite games of all time though are definately FF and I will buy a ps3 once XIII comes uot but still not #1.
